ABSTRACT.
After analyzing the existing methods of parameter estimate, the logistic model has been redesigned, and its matrix expression has been obtained. And then it has been applied to polytomous scoring questions of academic competitions in colleges and universities. The correlation between several sets of variables are obtained, which has provided ideas and methods for the application of the simplified models in many fields.
